In the cutting-edge world, semiconductor metal oxides usually tend to have a high optical band gap (>3.0 eV), significantly acceptable for potential optoelectronic applications. The present study discusses the synthesize of pristine tungsten trioxide (WO) and Silver (Ag) doped WO (Ag: WO) thin films onto a glass substrate at 450 °C, with varying concentrations of Ag doping (2, 4, 6, 8 and 10 at.

A simple and inexpensive spray pyrolysis deposition (SPD) approach was used to produce TiO and Cr (2-8) at.%-doped TiO thin films. To explore the morphological features of the films, FE-SEM micrographs were used and found that 6 and 8 at.
